The Catalog is an index of the maps and geographic data available throughout the Oakland County Web site. Much of the information is cataloged under the Maps & Data section, including:

• free maps that can be downloaded and printed
• maps that can be ordered online
• interactive, web based maps
• map publications and data products that can be ordered or downloaded

All maps and geographic data use Geographic Information Systems (GIS). Technical information about GIS is available under Data Models and Metadata.
